Restructured networking portions of installation guide

As part of the installation guide improvement project, I performed
the following operations on the networking portions of the
installation guide:

1) Created "generic networking" chapter directly after Nova chapter.
2) Migrated Neutron chapter to "generic networking" chapter.
3) Migrated "configure networking" section of Nova chapter to
   "generic networking" chapter.
4) Temporarily unlinked "Neutron deployment use cases" section of
   Neutron chapter.
5) Modified links affected by these changes.

This patch primarily addresses structural changes to improve
document flow. Future patches will address content affected by
these changes.
